γ′-Fe4N薄膜的制备及其磁性

Abstract

Abstract: The Fe-N thin films were deposited on single crystal NaCl(100) and glass substrates via DC magnetron sputtering with an Ar/N₂ gas mixture (N₂/(Ar+N₂)=10％) as the discharging gas. Thestructure, morphology and magnetic properties of the films were characterized by means of X-ray diffraction(XRD), Atomic force microscope (AFM) and superconducting quantum interference device (SQUID). The effects of substrate and substrate temperature on the structures and magnetic properties of the thin films were investigated. It was shown that the substrate temperature of single phase γ′-Fe₄N deposited on NaCl (100) substrate was lower than that on glass substrate. The formation temperature scope and magnetization of single phase γ′-Fe₄N on NaCl (100) substrate are all increased.

Key words: Fe-N thin films, structure, magnetic properties
